AC loss in large-scale superconducting cables [PDF]
, 1993 A review is given of recent work on ac losses, carried out at our institute. The emphasis is on large-scale conductors for fusion applications, such as the `cable-in-conduit¿ prototype conductors to be used for NET.

Analysis of AC winding loss of permanent magnet synchronous traction motor with high power
机车电传动, 2022 In a multiple-pole and high-power PMSTM with high fundamental frequency, the harmonic frequency of the internal magnetic field increases accordingly. The harmonic magnetic field will induce eddy current in the winding, resulting in high-frequency eddy ...

Universal dielectric loss in amorphous solids from simultaneous bias and microwave field
, 2013 We derive the ac dielectric loss in glasses due to resonant processes created by two-level systems and a swept electric field bias. It is shown that at sufficiently large ac fields and bias sweep rates the nonequilibrium loss tangent created by the two ...

A loss-less superconducting kilo-oersted ac magnetic field system [PDF]
, 1977 A simple superconducting system which allows almost loss-less ac magnetic field to be generated in the kilo-oested region and in the frequency range from dc up to more than 1 kHz is described. The behaviour of commercially available superconducting wires
